Test: Sensitivity & Thixotropy of Clays - Question 1

The degree of disturbance of undisturbed sample of clay due to remoulding is expressed by______

Detailed Solution: Question 1

The activity of clay is related with the plasticity and the quantity of clay-size particles. Thixotropy is the phenomenon of ‘strength loss – strength gain’. The density index is used to express the relative compactness.

Test: Sensitivity & Thixotropy of Clays - Question 2

The sensitivity of honey comb structure of clay is ______

Detailed Solution: Question 2

The classification of clays based on sensitivity is given by,

Test: Sensitivity & Thixotropy of Clays - Question 3

The larger the sensitivity, ______ the thixotropy hardening.

Detailed Solution: Question 3

Sensitivity is the degree of disturbance due to ‘remoulding’ and the thixotropy is the process of softening of clay due to ‘remoulding’, followed by time-dependent gain in strength. So, it can be said that they are directly proportional to each other.

Test: Sensitivity & Thixotropy of Clays - Question 4

Remoulding of clay results in _______

Detailed Solution: Question 4

The strength of a clay soil is related to its structure. Due to the destruction of the clay particle structure that was developed during the original process of sedimentation, there is loss of strength of clay soils.

Test: Sensitivity & Thixotropy of Clays - Question 5

Sensitivity is defined as _____

Detailed Solution: Question 5

The Sensitivity is defined as the ratio of unconfined compressive strength in natural state to that in remoulded state.
St = qu(undisturbed) / qu(remoulded)
